Ko te "tere rere tīmatanga" (e kiia ana ko Q₁ i roto i ngā paerewa ine) e tautuhia ana ko te tere rere wai iti rawa e taea ai e te mita wai miihini te tīmata i te hurihanga o tana tikanga ine ā-roto (hei tauira, te impeller) me te mahi ine rōrahi tika.
Ko ngā whakaritenga hangarau matua e whai ake nei:
- I te tere rere tīmatanga Q₁, me tutuki te hapa ine o te mita i ngā rohe kua tohua e tōna akomanga tika (hei tauira, ±5% mō ngā mita Akomanga 1 me ±3% mō ngā mita Akomanga 2 e ai ki te ISO 4064-1:2014).
- Me whakaatu e te mita te tīmatanga tairongo me te kore e aukati, e hysteresis rānei, kia tika ai te ine i ngā āhuatanga rere tino iti (pēnei i te wai e maturuturu ana) e kitea ana i roto i ngā tono whare, arumoni māmā rānei.
- Ka whakatauhia te uara o te tere rere tīmatanga mā te whakamātautau paerewa, e hiahiatia ana kia rēhita tonu te mita i te rōrahi tāpiri ina rere te wai i te Q₁, me te kore he whakaroa nui, he kore rānei e tīmata te ine.
He mea nui ēnei whakaritenga hei ārai i te whakamahinga wai kāore i tuhia, hei whakarite hoki kia tutuki te mita i ngā ture ine wai.
